Pelvic ROTATION
Summary
Pelvic Rotation measures the average angular
rotational range of the pelvis.
DETAILS
Pelvic Rotation is the average angular rotational
range of the pelvis, measured at the sacrum once
per second. This measurement is dependent
on the sacrum’s local vertical axis, which will be
perpendicular to the ground when sitting up, and
may tilt toward the handlebars when in riding
position.
This motion can also be described as the anterior
to posterior rotation of the pelvis along the
transverse plane.
A larger Pelvic Rotation value indicates greater
average rotation of the pelvis, and a lower value
indicates more limited average rotation.
SCORE
Each clockwise and counterclockwise rotation
occurring within each second is recorded and
then averaged.
